The area of the shape is 35 square units
<h3>How to determine the area of the shape?</h3>
The given shape is a trapezoid, and it has the following side lengths
Parallel bases = 6 and 8
Height = 5
The area of the shape is then calculated as:
A = 0.5 * (sum of parallel bases) * height
Substitute the known values in the above equation
A = 0.5 * (6 + 8) * 5
Evaluate the product
A = 35
Hence, the area of the shape is 35 square units

3x² - y³ - y³<span> - z
= </span>3x² - 2y³ - z
= 3(3)² - 2(-2)³ - (-5)
= 3*9 - 2(-8) + 5
= 27 +16 + 5
= 48
